解剖外动脉旁路移植术治疗主髂动脉闭塞症

Extra-anatomic arterial bypass grafting in the management of aorta-iliac occlusive disease

目的探讨解剖外动脉旁路移植术在治疗主髂动脉闭塞症中的作用。方法回顾性分析经解剖外动脉旁路移植术治疗的41例主髂动脉闭塞症患者的临床资料，其中有间歇性跛行11例，下肢静息痛12例，合并溃疡或坏疽18例。15例腹主动脉和（或）双侧髂动脉闭塞者采用腋.股动脉旁路移植术，18例单侧髂动脉闭塞者采用股.对侧股动脉旁路移植术，8例单侧髂动脉合并同侧股动脉闭塞者采用股.对侧胭动脉旁路移植术。使用的旁路移植血管均为聚四氟乙烯（Gore-Tex）人工血管。结果术后40例（97.6％）患者的临床表现明显改善。踝肱指数由术前0.41±0.15升为术后0.89±0.21，两者比较差异有统计学意义（P〈0.05）。随访35例，随访时间1-5年，本组术后1、3、5年移植血管的总的通畅率分别为93％、86％、80％。结论解剖外动脉旁路移植术具有创伤小，术后恢复快等优点，是治疗主髂动脉闭塞症的有效方法之一。

Objective To study the role of extra-anatomic arterial bypass grafting in the management of aorta-iliac occlusive disease. Methods Forty-one cases of aorta-iliac occlusive disease managed by extra-anatomic arterial bypass grafting were retrospectively analyzed. Clinical features included claudication 11, resting pain 12 and ulcer/gangrene 18 patients. Axillofemoral bypass was performed in 15 cases with aortic and bilateral iliac artery occlusion, femorofemoral bypass in 18 cases with unilateral iliac occlusion and popliteal bypass in 8 cases with iliac and ipsilateral femoral artery occlusion. Results Postoperatively, clinical features were relieved in 40 cases （97.6%）. Ankle brachial index increased significantly from 0.41±0.15 to 0.89±0.21 perioperafively （P〈0.05）.Thirty-five cases were followed up for 1 year to 5 years. The overall graft patency rates in this series were 93%, 86% and 80% in 1, 3 and 5 years, respectively. Conclusion Extra-anatomic arterial bypass has merits as less invasive and rapid postoperative recovery, and this is one of the effective methods for the treatment of aorta-lilac occlusive disease.
